新办公楼装修，布线选超五类还是六类？...

<p>单位买了两层楼面做新办公楼，现在要准备装修布线，大家说说选超五类还是六类布线啊？六类的比超五类的贵多少？</p><p>目前情况：政府事业单位，人员70人，每人一台电脑，用CISCO 2924/2950交换机组成局域网，通过cisco 路由器，防火墙，电信10M光缆连互联网。内部主要业务有OA，Oracle 数据库等等，将来可能有部分机器有视频业务（类似于流媒体点播）。</p><p></p><p>另外：原来局域网是通过在2924/2950下级联交换机的方法扩展端口的，现在重新布线了，我想再买几台2950做堆叠，是否可行？2924/2950到底支持不支持堆叠啊？如果可以，要增加什么硬件？费用大致多少？</p><p>btw,语音到底要不要用网线布啊？</p><p>新人初来，不懂的太多，请大家赐教。</p><p>谢谢！</p><p></p><p></p>

<p>布线方面，六类比超五类大致要贵50%左右。</p>

<p>楼对说的对，你70个点用超5类我估计吗2-3万左右应该就可以了，要是用6类肯定要贵一倍。另外你现在用的是2950的交换机，也都是10/100M的口，跑不了1000M，你做6类基本没什么意义。我建议你从经济的方面出发吗，在买交换机时买台高点1000M的做核心，1000M接服务器对你跑数据肯定是没问题的。要是还想节省点就买2950T的带1000M也没什么问题的。不过你事业单位有钱可全部换成1000交换机在做6类布线，这样可以桌面到1000M了。</p>

从长远来说，放六类线还是比较好的，以后想走1000M的话只换交换设备就好。

<p>既然是政府单位么当然要用6类线，对大家都有好处，呵呵！</p><p>我们公司做了好多政府单位工程，现在几乎全是6类：IBM、SYSTIMAX等产品。</p>

<p>6类是趋势</p><p></p><p>但六类也不能达到千兆带宽</p>

<p>5E就可以传1000M了，干吗非要六类？</p><p>2950要淘汰了，这个就别考虑了，用2960吧，价位相差不是很大，不过商家一般都推荐2950，因为是马上要淘汰的产品，利润空间很大，也有存货方面的压力</p><p><table cellspacing="0" cellpadding="0" width="593" border="0" style="WIDTH: 445pt; BORDER-COLLAPSE: collapse;"><colgroup><col width="151" style="WIDTH: 113pt;

<p>不知道楼主是那里的，可以多多交流。</p><p></p>

<p>正常有超五类就足够了,就是100M你还不知道什么时候能达到能,1000M只是一个概念,不信你可以看看哪个单位能实际用100M,用超五类按140个点有6万就全够了,可用六类没有10万肯定是不够的,还不算交换机的钱.</p>

可以来和我们联系我们可是品牌厂家啊

<p>用6类的吧,因为你要上视频</p>
